Liquid filler

ABSTRACT

An improved construction of a liquid filler comprised of a filling body, a ball valve, and a mobile lid shutter that executes automated and precise filling operation in a summary structure of having an oil flow control valve and oil exhaustion channel installed on a same filler body for achieving economic and practical benefits by lowering production cost and minimizing failure, and provides safety protection benefits by cutting off flame of any accidental ignition of the oil in the barrel from extending back into the oil tank.

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention is related to a liquid filler to load volatile oil from oil tank to an oil barrel, and more particularly, to one that prevents accidental flame breaking out in the barrel from extending into the oil tank.

(b) Description of the Prior Art

Whereas a filler of liquid is essentially used in distributing oil from oil tank into an oil barrel, gas generated from the volatile oil in the course of transport will increase the pressure inside the oil barrel. An exhaustion pipe is separately provided to collect the gas above the liquid level inside the barrel into another barrel for reuse. A liquid filler 2 of the prior art as illustrated in FIG. 1 of the accompanying drawings has one end installed at a terminal of an oil pipeline 3 extended from an oil tank and another end inserted into a liquid inlet 41 of an oil barrel 4. A flow-regulating valve 22 is disposed to a middle section of the filler 2 to control the oil S flowing into the barrel 4. Exhaustion and collection installations generally available include an exhaustion pore 211 provided on one side of a lower section of a liquid outlet pipe 21 extending into the liquid inlet 41 of the barrel 4; a rear end of the filler 2 extends to connect to a connection pipe 23 for gas collection and turns to extend into the liquid outlet pipe 21 for series connection to define a pathway for oil gas S1 separately provided on the inner side of the liquid outlet pipe 21. Accordingly, oil gas S1 generated above the level of the oil is pushed to the exhaustion pore 211 and externally discharged through a gas outlet 212 and the connection pipe 23.

However, the connection pipe 23 for discharging and collection the oil gas S1 and the filler provided with a flow regulating valve 22 in the construction of the liquid filler of the prior art are separately provided to consume additional space and cause barrier to the hands of the operator. Furthermore, the tail of the connection pipe 23 must be curved to extend into the exhaustion pore 211, and the air outlet 212 before a total welding job to where the tail of the connection pipe 23 enters into the exhaustion pore 211 and the air outlet 212 that involves extra time and inconvenience in the process. Defects frequently found at where the soldering job is provided lead oil S leakage from the peripheral of the soldering seam.

Furthermore, the liquid outlet pipe 21 of the filler is open-end to easily attract the flame in case of accidental ignition of the oil in the barrel 4 to extend back into the oil tank for causing more serious explosion.

SUMMARY OF THE INVENTION

The primary purpose of the present invention is to provide an improved construction of a liquid filler that features a summary structure of having an oil flow control valve and oil exhaustion channel installed on a same filler body for achieving economic and practical benefits by lowering production cost and minimizing failure. To achieve the purpose, the present invention includes a filling body containing a hollow valve chamber; a ball valve disposed at the upper end of the filling body is provided with an axial bolt to execute turning direction around a fixed axial; a liquid inlet and a downward liquid outlet provided sideway at the middle section connect through the ball valve to receive oil introduced through a liquid receiving pipe disposed on one side of the filling body; the lower section of the valve chamber is made downward; a liquid drain pipe provided with a coupling seat is externally disposed to the middle section of the valve chamber; a liquid drain channel to receive oil from the oil outlet of the ball valve and lead the oil to flow into an oil barrel placed below the liquid filler, and an exhaustion channel with a closed terminal are segregated inside the liquid drain pipe; an oil gas inlet is disposed on one side of the lower section of the exhaustion channel and an oil gas outlet externally connected to an oil gas outlet is disposed on the upper section of the exhaustion channel for discharging volatile oil gas present above the liquid level in the oil barrel along the exhaustion channel.

Another purpose of the present invention is to provide an improved construction of a liquid filler that provides safety protection benefits by cutting off flame of any accidental ignition of the oil in the barrel from extending back into the oil tank. To achieve the purpose, a drooping mobile lid shutter is disposed by having its top pivoted to a mouth at the bottom of the liquid drain channel in the lower section of the filling body; the mobile lid shutter is connected to a tension coil suspended in and extending from the inner side of the liquid drain channel; and the mobile lid shutter normally blocks the mouth of the liquid drain channel in the absence of executing liquid discharge by the mobile lid shutter.

Another purpose yet of the present invention is to provide an improved construction of a liquid filler that executes automated and precise filling operation. To achieve the purpose, once the coupling seat moves further to cover up the liquid inlet of the barrel in position, a plate retainer at the top of the mobile lid shutter protruding from where behind the pivoting location at the top folds up for holding against the edge of the liquid inlet of the barrel, in turn synchronously opens up a front section of the mobile lid shutter to automatically open up the mouth of the liquid drain channel; and when the coupling seat upward clears away from the mouth of the liquid inlet of the barrel, the plate retainer for no longer holding against the edge of the liquid inlet of the barrel folds downward to return to its normal status of shutting up the mouth of the liquid drain channel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1, 2, 3, and 4, an improved construction of a liquid filler of the present invention is essentially comprised of a filling body 5, a ball valve 6, and a mobile lid shutter 7.

The filling body 5 contains at its middle section a hollow valve chamber 51 provided with a bolted opening at its top; an open liquid inlet 52 is provided on one side of the valve chamber 51 for an outer end of the liquid inlet 52 to be connected to a liquid pipe 55 extending from an oil tank so to allow oil S delivered form the tank to enter into the valve chamber 51 through the liquid inlet 52; a lower section of the valve chamber 51 is directed downward; and a liquid drain pipe 53 connected to a coupling seat 531 to an oil barrel 4 is externally disposed to the middle section of the valve chamber 51.

The ball valve 6 inserted in the valve chamber 51 is provided at it top a regulating axial bolt 61 to pass through a bolting hole 541 disposed in a middle section of a locking lid 54 located at where above the valve chamber 51 for the ball valve 6 to execute turning its direction around a fixed axis when a handle 62 is connected to the ball valve 6. The middle section of the body of the ball valve 6 is made a sideway liquid inlet 63 that connects through a downward liquid outlet 64 to receive the volatile oil S introduced from a liquid receiving pipe 55 provided on one side of the filling body 5. A liquid drain channel 532 directed downward to receive liquid delivered through the liquid inlet 63 of the ball valve 6 is segregated in an inner section of the liquid drain pipe 53, and the terminal of the liquid drain pipe 53 is related to a closed exhaustion channel 533. An inlet 5331 for an oil gas S1 is disposed on one side of a lower section of the exhaustion channel 533, and an outlet 5332 to drain the oil gas S1 externally connected to a gas-leading pipe P is disposed in an upper section of the exhaustion channel 533. Accordingly, the volatile oil-gas S1 above the oil level of the oil S is externally led along the exhaustion channel 533 to achieve the purpose of providing a summary construction of having a flow control valve (i.e., the ball valve 6) for the oil S and a drain channel for the oil gas S1 (i.e., the exhaustion channel 533) disposed on the same filling body 5.

The mobile lid shutter 7 is pivoted to an upper section of a mouth at a bottom end of the liquid drain channel 532 by means of a lateral bolt 71 disposed on its top and further connected to a tension coil 72 extending out of the inner side of the liquid drain channel 532 so that the mobile lid shutter 7 normally shuts up the mouth of the liquid drain channel 532. A plate retainer 73 protrudes from the top of the mobile lid shutter 7 at where behind the pivoting location of the lateral bolt 71.

Accordingly, as illustrated in FIG. 4, before the coupling seat 531 moves to a locating position to fully cover up a liquid inlet 41 of the barrel 4, the mobile lid shutter 7 normally shuts off the mouth of the liquid drain channel 532 when the tension coil 72 is pulled up and the oil S delivered from the oil tank is prevented from being led downward even the liquid inlet 63 of ball valve 6 has been turned to align at the liquid inlet 52 of the filling body 5.

Once the coupling seat 531 moves further to cover up the liquid inlet 41 of the barrel 4 in position as illustrated in FIG. 5, the plate retainer 73 at the top of the mobile lid shutter protruding from where behind the pivoting location at the top folds up for holding against the edge of the liquid inlet 41 of the barrel 4, and in turn synchronously opens up a front section of the mobile lid shutter 7 to automatically open up the mouth of the liquid drain channel 532. The oil S is downward led to enter into the barrel to complete the purpose of filling the oil S into the barrel 4 when the liquid inlet 63 of the ball valve is turned to align at the liquid inlet of the filling body 5.

As illustrated in FIG. 4, when the coupling seat 531 upward clears away from the mouth of the liquid inlet 41 of the barrel or the barrel 4 turns over for the coupling seat 531 to automatically disengage from the mouth of the liquid inlet 41, the plate retainer 73 for no longer holding against the edge of the liquid inlet 41 of the barrel 4 folds downward to return to its normal status of shutting up the mouth of the liquid drain channel 532 to prevent the oil S from being further led into the barrel 4 to provide safety protection benefits, i.e. the most important characteristic of the present invention in case of an accidental ignition breaks out inside the barrel 4 by cutting off extended ignition of fire or explosion since the fire is prevented from spreading through the liquid drain channel 532 back to the filler and the oil tank at the front end of the filler.
